For many uses, market value more accurately represents the debt burden faced by the U.S. government than the par value. The par value of government debt, which is reported by the U.S. Treasury Department, reflects interest rates at the time the debt was issued while the market value is adjusted to reflect market interest rates as of the observed period. Federal Reserve Bank of Dallas researchers calculates the market value of U.S. government debt series. For further information visit http://www.dallasfed.org/research/econdata/govdebt.cfm.

Write a custom formula to transform one or more series or combine two or more series.

You can begin by adding a series to combine with your existing series.

Now create a custom formula to combine or transform the series.

For example, invert an exchange rate by using formula 1/a, where “a” refers to the first FRED data series added to this line.
Or calculate the spread between 2 interest rates, a and b, by using the formula a - b.

Use the assigned data series variables (a, b, c, etc.) together with operators (+, -, *, /, ^, etc.), parentheses {(,)}, and constants (1, 1.5, 2, etc.) to create your own formula (e.g., 1/a, a-b, (a+b)/2, (a/(a+b+c))*100).
As noted above, you may add other data series to this line before entering a formula.
